Hi,
if you press STRG and right click in a xterm you can change the size of the
text/xterm. This however is not possible with the beta install. This is
because the font used by the xterm is missing. I however do not know
exactly which font is missing. (I had this problem before with a bare
FreeBSD installation and after installation of several fonts from the ports
the problem disappeared.)
Best regards,
Martin Laabs
